74LS Low Power Schottky Logic IC's

74LS Low Power Schottky Logic IC's

The Low Power Schottky (LS TTL) logic IC family is similar in function to the original 7400 series TTL family. It has the same propagation delay as the 7400 series,  but current and power reduction are improved by a factor of 5. This is accomplished by using Schottky diode clamping to prevent saturation and advanced processing. 74LS IC’s were used very widely in the 70’s, 80’s, and 90’s, and devices in this family were available in a wide range of functions. The devices can operate between 7.75 and 5.25 VDC,m with 2mw typical dissipation. Typical gate delay is 10 ns. Most of these devices are now discontinued.

These 74LS series listings are standard DIP IC's. Most packages are 14 and 16 pins, but some devices are larger.

• Most of these listings have no individual photos, but do indicate package type. In almost all cases our generic part number will be enough to match the part you need, but to confirm a correct match, click on the listing and check the package type in Overview section.

• About 90% of these items are from major manufacturers like Texas Instruments, Motorola, Dallas, Fairchild, Hitachi, National, NEC, etc., but some are unbranded or from minor manufacturers. All parts are unused and fully guaranteed. Some older parts show age from long-term storage, but this will not affect proper operation. None of our parts are counterfeit or B stock.

• You can always use the search box to find a specific part, but it's best to use the basic, generic part number, with no prefix or suffix.

• If you can’t find what you need, please ask. Contact us.
